Ok, I am finally switching from 1 weekly IM injection (23G 1 inch) to twice a week schedule. My wife has boxes of 1ml 5/16 31g slin pins. So …
Can I use those to start (too thin too short?)? And if so, can I go straight into my quads/delts with that length?
Where are the best SubQ injection locations?
Does it matter how deep injection is … i.e, will shallow IM work as well as SubQ?
